Carolina geranium is a winter annual or biennial weed that is also called cranesbill because the fruits have a conspicuous “beak” about ½ inch long. The flower is white to lavender. It blooms mostly in April and May.
The flowers are a good nectar source. Seeds are food for birds, especially ground feeders such as doves and quail, and for small mammals such as rodents. The seeds are reported to have astringent, diuretic and nephritic properties.
